A method for determining a thickness of an item comprises controlling a device to apply a magnetic pulse to the item and acquiring a signal reflecting a time dependence of an eddy current decay in the item caused by the magnetic pulse. The method further comprises calculating a first thickness of the item based on a set of samples in the signal and calculating a first resistivity of the item based on a first set of samples. The method additionally comprises calculating a second resistivity of the item based on a second set of samples and determining a compensation factor based on a difference between the second and first resistivities. The method also comprises calculating a thickness of the item based on the first thickness, a relation between the first thickness and the first resistivity, and the compensation factor. An output of the thickness of the item is then provided.
